My invention relates particularly to means for installing what iscommonly termed an outboard motor inside of a boat.

One object is to provide a simple and in- 55 expensive construction"involving improvements on the invention of my Patent 1,786,997.

A special object is to provide a simplifiedmounting for the motor in thecasing. Another object is to provide means of construction such that themotor can be readily removed or installed in the casing.

Another object is to provide an improved automatic drain. I Anotherobject is to provide means for draining the boat as well as the casingwhen the boat is in motion.

Fig. 2 is a transverse section of a boat on a very small scale showingan installation em- 'bodying my invention. Fig. 3 is an enlarged crosssection of the casing showing the drains and engine exhaust.

Fig. 4 is a transverse section of the pro- 4 peller housing.

Fig. 5 is a plan view of the casing and Showing the propeller housingand frame in section.

Fig. 6 is a diagrammatic .plan of a modification.

The casin may be formed of suitable material such or instance as castmetal having a side wall 7, a bottom wall or floor 8 and .a projectinflange 9 for attachment to the bottom of a %oat or the walls mightbeparts of f the boat structure. The bottom of the casing has an opening10 in its rear end which is preierably circular, and which is normallyclosed by bottom plate 11. A resilient asket 12 to instance, of rubber,serves as g g I a yielding s pport for the bottom plate and attachedparts. I

The motor 14 may be of any suitable type usually provided witha controlhandle such as 15, and with-the cylinders and fly wheel at the top.The-vertical housing 16 contains the shaft and gear connection to thepropeller 17 and supports the motor cylinders and associated parts. Themotor may be supplied with coolin water for instance, through a pump 18.he propeller shaft housing may also carry the exhaust passages and havean outlet such as 19. The guard 20 serves to protect the pump andpropeller. Features of the housing 16 and its various passages are morefully shown and claimed in my appliso cation 582,980, filed December 24,1931.

The motor is supported by a frame of which the bottom plate 11 is a art.The sleeve 21 in which the propeller ousing 16 is supported andpreferably rotates is secured to the bottom plate in any suitablemanner,

for instance by a flange 22, which may be riveted, bolted, welded orintegral with the bottom plate preferably at its front ed e. A bracketor arm 23 has upper and ower branches at its rear end secured forinstance by cap screws 24, to the front side of the a sleeve 21 at itsupper and lower ends respec-v tively. The front end of this bracket ispiv otally' supported by lugs 25, which may be, 7 cat integrally withthe bottom and front wall of the casing. The pivots are formed by pinssuch as 26, which are detachably mounted in the lugs 25 so that they maybe readily retracted for disconnecting the arm from the casing. Thesepins may have finger pieces 27,

to facilitate retraction and they ma be supported by sprin strips 28 forholding them yieldingly and etachably in position. The

upper part of the sleeve 21 is preferabl split and provided withflanges3O adapte to be drawn toward each other bya screw 31, so

as to vary the frictional resistance of the shaft housing inside thesleeve and thus control the resistance to rotation of the engine andpropeller on a vertical axis. The propeller housing has a collar 32,which rests 'on the upper end of the sleeve 21 to support the welght ofthe motor and'propeller. The length of the. bracket 23 is referably lessthan'the height of the casin i so that the motorand tliepropeller may etilted about'the single axle of. the hinge pins 26 in such a manner thatthe propeller and the lower end of the housing can be retracted within aspace. 10o

1 drain outlets is' preferably -connected by means of a ipe 37, to theinside of the boatv outside of t e casing where a screened inlet 38, isprovided. This pipe 37 maybe a flexible rubber hose secured on to theend of a nipple 39;, projecting upwardly from the suc-' tion outlet 36.

i The motormountmg is so constructedthat it maybe readily tilted intothe dot and dash line of Fig. I for the purpose ofinspection,

' Q repair, or replacement of the propeller. The

.7 motor will also automatically be thrown into this position in casethe propeller housing or guard. strikes an obstacle. When the obstaclestrikes the guard 20, the tendency is to swing the propeller housing andmotor about the pivot 26, and as soon as the arm 23 is raised at all,the forward inertia of the motor and the upper end of the propellerhousing tends to move these parts forwardl so that the retracting actionis facilitate by the check- I in of the movement of the boat.

is in motion. In this construction the casing 7 is preferably. open atthe to so that any leakage of or oil from t e motor, or its supply- 4tank, can-fall directly into the casing and not "into the boat. When theboat is moving the water in the easing as well as the water outside ofthe casing, but inside of the boat, is drawn out through the suctionoutlets and 36 so as to maintain buoyancy and dryness of the boat andcasing. I

For transportation purposes it is a very simple and quick matter todetach the entire 'motor and its supporting frame by simply retractingthe pins 26 b one hand.

By locating both oft e drains in the bottom of the movable plate, itwill be seen that they are both automatically lifted clear of the bottomof the boat when the-motor is lifted and the bottom of the boat isthusleft clear and free from obstructions.

In the form shown the casing is provided with downwardly projectinglongitudinal ribs 40 extending substantially the length of the casingfrom front to rear on each side.

These ribs serve several functions, i. e.,- reinforcement to the casingper se, guards to rotect -the' drain-outlets, and stabilizing eelsectlons- These ribs may be cast integral 'ly' with the casing and whilethey add very "bottom of said casing to en the motor is dropped downinto place the gasket 12 serves as a cushion to prevent shock. This alsomakes it possible to main- 35 mm a nearly water-tight seat when the boatneveesa little to the amount of'metal required they materiallystrengthen the bottom of the easmg. a Y In smaller boats the casingmight 'fill the entire width of the boat, or the rear or other portionof the boat might constitute the casing. In such a case transversebulkheads d1,

42 might constitute the front and rear walls v of the casing, and thesides &3 of the*boat or longitudinal bulkheads might constitute the sidewalls. The motor frame,the supporting plates, the drainage and thetiltin action would be the same as above describe I claim: 4
